Frame generation

Type in either box and the other updates. Frame generation multiplies the displayed rate from the rendered rate you enter.

Frame time

Frame generation and input lag

Frame time is 1000 divided by FPS. Latency also depends on the game, display and input device.

Why milliseconds matter

A frame rate is an average over a second. Frame time is how long each frame takes, and it is what you actually feel. The same average can hide stutter, and a lower frame time means newer information reaches your eyes sooner. The table below shows common targets.

Frequently asked questions

How do I convert FPS to milliseconds?

Divide 1000 by your frame rate. At 60 FPS each frame takes about 16.7 milliseconds, at 120 FPS about 8.3 milliseconds and at 240 FPS about 4.2 milliseconds. To go the other way, divide 1000 by the frame time in milliseconds.

Is frame time more important than FPS?

Frame time shows how smooth the game feels because it reveals uneven frames that an average FPS hides. Two games can both average 60 FPS while one has steady 16.7 millisecond frames and the other spikes. Consistent frame times feel smoother and more responsive.

Does frame generation reduce latency?

No. Frame generation raises the displayed frame rate but input is still processed on the rendered frames, so responsiveness follows the rendered frame time and can be slightly worse. That is why a base of 40 to 60 FPS before frame generation is recommended.

What frame rate matches my refresh rate?

Ideally the frame rate meets or exceeds the refresh rate, for example 144 FPS on a 144 Hz monitor. With variable refresh rate, frame rates below it still look smooth. The converter shows the time budget your GPU has for each frame at your refresh rate.
